“Up to now 5 years, OpenAI’s GPT-3 learns common sense information, and o1 makes use of reinforcement studying to assume earlier than responding, considerably enhancing reasoning abilities in coding, knowledge evaluation, and sophisticated math,” the submit mentioned.
“Nevertheless, the resultant fashions are nonetheless probably not normal: a few of them are good at coding, some good at math, and a few good at reasoning, however none of them may obtain the perfect efficiency throughout all of the totally different duties,” it mentioned in its submit. “GLM-4.5 makes efforts towards the purpose of unifying all of the totally different capabilities.”
OpenAI has said that its subsequent mannequin, GPT-5, anticipated by the top of summer season, shall be its first totally unified software.
Within the meantime, GLM-4.5 and its smaller sibling GLM-4.5-Air scored a mean of 63.2 and 59.8 throughout 12 business assessments, rating third globally, behind OpenAI o3 and Grok-4.
The fashions make use of a Combination of Specialists structure with a complete of 355 billion parameters for the flagship model. Nevertheless, solely 32 billion are lively at any given time, making it extra environment friendly than brute-force approaches.
GLM-4.5 achieved a 90.6% tool-calling success fee, outperforming Claude 3.5 Sonnet’s 89.5% and even Kimi K2’s 86.2%.
On internet searching duties, it accurately answered 26.4% of complicated questions in comparison with Claude 4 Opus’s 18.8%. The mannequin solved 98.2% of issues within the MATH 500 benchmark, matching Claude 4 Opus, all whereas being open supply.

Z.ai costs API calls at $0.11 per million enter tokens and $0.28 per million output tokens—roughly one-fifth the price of comparable Western fashions. The corporate launched the weights below an MIT license on Hugging Face and GitHub, permitting anybody to obtain and modify the code.
The fashions function what Z.ai calls “hybrid reasoning” with two modes.
A pondering mode handles complicated reasoning and planning duties, whereas a non-thinking mode gives instantaneous responses.
The corporate shared samples of how individuals can construct whole web sites with pure language instructions or generate interactive visualizations starting from Pokémon databases to complicated shows.
Chinese language corporations are accelerating their funding in AI, releasing 1,509 massive language fashions as of July 2025, which represents 40% of the three,755 fashions launched globally and affords among the finest open-source fashions within the business.

Hidream-I1 is the perfect open-source picture generator with Hailuo, Seedream, and Kling beating among the largest names within the generative video scene.
Early traders of Z.ai embrace Alibaba Group, Tencent Holdings, and HongShan Capital Group.
